How to disable USB 1.1 ports?

I need some wisdom from heavy duty geeks.
I run Win XP SP3 on a Soyo Dragon 2 motherboard. The motherboard is spec-ed for 8 USB ports but my PC brings out only 6 ports; 4-USB 2.0 and 2-USB 1.1. I use a program that uses USB but selects the slowest available in the machine, so it runs on the USB 1.1 and the slowness drives me crazy. I have no use for the USB 1.1 ports at all. Is there a way that I can disable those ports so that my program will not see them and hopefully run on the 2.0s. I am including a pic of my device manager in the hope that someone can tell me what and how to disable the dinosaurs.

I tried that but the program just hung. I know that it can work with usb 2.0 because I run it on my laptop that has only usb 2.0 ports and it runs at the faster speed. Somehow I have to make the program think that there are no usb 1.1 ports in this computer. Maybe usb infrastructure is more complex that I imagine. Stiil, I would appreciate any ideas from folks who have dealt with such issues.

Try this. With no devices plugged into the 1.1 USB ports, right click one of the USB root hubs and select Properties, then Power. Note which hubs have no devices. Plug a device into the 1.1 port. Repeat the procedure seeing which hub has a device now. That should be the hub to disable. After you remove the device and disable the hub plug the device into the other 1.1 port just to make sure it is disabled too.

Thanks to mrjimphelps and joep517. I found the enable/disable usb in the BIOS. But the trick of plugging a usb 1.1 device in the ports and checking the power tab in the usb hub properties allowed me to map the hubs to the 1.1 ports. I diabled those drivers and that did it.
